Description

Technical Field

[0001] This utility model relates to the field of extruder screw processing technology, and in particular to a heat treatment device for extruder screw processing. Background Technology

[0002] The extruder screw plays a crucial role in the extruder. It mainly consists of the screw and the screw barrel. By rotating the screw, thermoplastic materials such as plastics and rubber are transformed from a solid to a molten state, and then shaped into the desired form through the extruder die. Heat treatment of the extruder screw during processing is primarily to improve its material properties and enhance its wear resistance, strength, and corrosion resistance. The heat treatment unit quenches the screw, thereby achieving a high surface hardness and improving its wear resistance and service life.

[0003] Existing heat treatment devices for extruder screw processing have been found to have shortcomings during use. First, they cannot perform quenching treatment on the extruder screw in a timely manner after the heat treatment is completed. Second, they cannot drive the extruder screw to rotate around its own axis during the heat treatment and quenching process.

[0004] In view of this, the inventors hope to optimize and improve the existing heat treatment device for extruder screw processing. Summary of the Invention
